Thank you, yes, I filled the backer form, replied to email requesting the graphic choice, entered the KS code and even tried create a new profile to force again the profile creation. And I checked the special actions tab in skills screen. And I contacted support.
Well the problem is in last point. At first I believed the pet had to be found in the game and I delayed start play the game to wait first patches. So I realized the problem very late so contacted support late. And in that context I'm just an impatient kid, as because of the context I contacted support only Friday.

But I'm on starting block to play more the game and don't want spoil my fun of doing it with a pet. So I'm in the impatient kid mood, that's it.
Mmm I do hope it doesn't work just because it's the Mac version, I didn't bother try on Windows and don't want play it on Windows but if I can transfer saves it could solve my problem (or not).
